The Siemens 6GT2898-0AC21 is a 2 m power supply cable for connecting the SIMATIC RF600 wide-range power unit to a 125 V supply via a NEMA 5-15P US plug. It uses an SVT 18 AWG x 3 jacket, black sheath, with color-coded cores. The plug-in connection is a US plug / Mini-Change® female 3-pin, bolted for a secure fit. This is the specific cable for the RF600 power unit — not a generic replacement.
The 2 m length is enough to reach from a panel-mounted power unit to a standard wall outlet without excess coil. The NEMA 5-15P plug mates with any US 15 A receptacle. The SVT jacket is flexible for routing through cable glands or wireway.
